贝氏体相变理论新进展及学术分歧

AN OVERVIEW OF RECENT PROCESSES AND ARGUMENTS ON BAINITIC TRANSFORMATION THEORY

介绍了贝氏体相变领域切变和扩散控制台阶长大理论的核心内容；论述了贝氏体相变理论领域的主要研究成果及争论焦点：涉及贝氏体定义、转变不完全性、溶质拖曳及类拖曳效应、表面浮突的形态、特征及本质、相变产物的晶体学、贝氏体铁素体初始碳含量、贝氏体“中脊”、下贝氏体碳化物来源及形成模型等．

The main points of view about shear and difusion for the bainitic transformation, which include some important research results and key controversial points,i.e., bainite definition, incomplete phenomenon, solute-drag and solute drag-like effects,the shape, characteristics,nature of the surface relief,crystallography,initial carbon content in bainitic ferrite, the so-called midrib of bainite, source and formation model of lower bainitic carbide,etc., were briefly reviewed
